[AGG] Want to calculate stroke of a path

[Shriramana S. <sa...@gm...>]

In my application I want to calculate the outer envelope of stroke of
a pen (like Inkscape stroke -> path). For this I presume I have to use
the adaptive subdivision formulae described at
http://antigrain.com/research/adaptive_bezier/ and at each point I
determine the normal vector to the curve and place points defining the
left and right edges of the pen according to that vector. Please
indicate how I can use AGG for that. Thank you!
